BOARD-CONNECTING ELECTRIC CONNECTOR

摘要

A good mating state can be obtained while reducing interference of transmission signals by a simple configuration. A contact portion is provided at a single location on each of mating recessed portions of signal contact members arranged in a multipolar shape, contact portions are provided at a plurality of locations for a mating recessed portion of an integrated power-source contact member, and signal transmission is carried out through the single-location contact portion provided at the single location for each of the mating recessed portions of the signal contact members. As a result, particularly, interference in high-frequency transmission is reduced to obtain good transmission characteristics, while sufficient mating retention force is configured to be obtained by causing the contact portions at the plurality of locations provided on the mating recessed portion of the power-source contact member to be in a state in which the contact portions are in contact with contact portions of a mating counterpart by the plurality of locations.

主权项

1. A board-connecting electric connector having a plurality of signal contact members arranged in a multipolar shape and a power-source contact member or a ground contact member attached to an insulating housing, the board-connecting electric connector configured so that contact portions provided on the signal contact members and the power-source contact member or the ground contact member are electrically connected to contact portions provided on a mating counterpart; the board-connecting electric connector comprising:
the signal contact members and the power-source contact member or the ground contact member each being provided with a mating recessed portion receiving the mating counterpart and provided with a solder connection portion extending from the mating recessed portion in a direction orthogonal to a direction of arrangement of the multipolar shape; the contact portion of the signal contact member being provided at a single location for each mating recessed portion of each of the signal contact members; and the contact portions of the power-source contact member or the ground contact member being provided at a plurality of locations for the mating recessed portion of the power-source contact member or the ground contact member integrated therewith.
